Osram Laser Brings Autonomous Driving One Step Closer

News
Higher power, more efficient pulse laser diode increases range of LIDAR applications

Osram Opto Semiconductors has announced a new pulse laser diode for a wide range of automotive LIDAR applications. The new SPL DS90A_3 laser is said to be more powerful and more efficient and increases the range of the applications.

The edge emitter scans the vicinity of the car with an infrared laser beam across a particular angle segment. The system uses the scans to create a high-resolution 3D map of the environment. This enables the technology to react to any traffic situation without losing valuable seconds. A car traveling at a speed of 50 miles an hour, for example, covers about 22 meters every second, so every extra second that drivers take to react can have serious consequences for them and other road users.

SPL DS90A_3 can be operated at high currents up to 40 A and achieves a typical output power of 125 W. The laser is suitably qualified for use in automotive applications and offers impressively long life and high efficiency. Its compact dimensions allow for flexible system design within the vehicle.

“With this new laser we have succeeded in taking one of the key technologies for autonomous driving another step forward. Thanks to the higher output, the LiDAR system can reliably detect even small and poorly reflecting objects at big distances and take the necessary action in critical driving situations”, said Andreas Bauer, marketing manager for lasers at Osram Opto Semiconductors.
